Abstract
The electromagnetic and radio-absorbing characteristics offerrite-polymer composites with conductive inclusions based on polyvinylalcohol are investigated. The Ni-Zn spinel ferrite powder of 2000NN gradewith composition Ni0.32Zn0.68Fe2O4 was used as filler. It is shown that theobtained composites are effective absorbers in the frequency range of 2-5 GHz with peak reflection loss less than ~20 dB. Through the analysis of thepermittivity spectra and permeability spectra, as well as the calculatedreflection loss spectra, critical factors of the electromagnetic waveabsorption in obtained composites are established. Keywords: polymer composite, radio absorption, nickel-zinc ferrite,polyvinyl alcohol\
